Relaxation and Mindfulness in Pain: A Review

Psychologically based interventions for adults with chronic neuropathic pain: a scoping review

OBJECTIVE

As psychologically based interventions have been shown to have clinical utility for adults with chronic pain generally, a similar benefit might be expected in the management of chronic neuropathic pain (NeuP). However, to date, this has not been established, with existing systematic reviews on this topic being hampered by the scarcity of randomized controlled trials (RCTs). This review aimed to identify the type of psychologically based interventions studied for adults with chronic NeuP. It also aimed to assess whether there are enough RCTs to justify undertaking an updated systematic review.

METHODS

Seven databases and 2 clinical trial registries were searched for NeuP and psychologically based interventions from database inception to December 2021, and the search was updated in February 2023. The search was broadened by reviewing the reference list of included studies and contacting field experts. Predetermined study characteristics were extracted.

RESULTS

Of 4682 records screened, 33 articles (less than 1%) met the eligibility criteria. Four broad intervention approaches were observed, including cognitive-behavioral approaches (n = 16), mindfulness/meditation (n = 10), trauma-focused therapy (n = 4), and hypnosis (n = 3). Thirteen RCTs were identified, and of these, 9 retained 20 participants in each arm after treatment.

CONCLUSIONS

Cognitive-behavioral therapy was the most common therapeutic approach identified, whereas mindfulness/meditation was the most frequently used technique. Almost half to two-thirds of the studies reported significant improvements in pain, disability, or distress, which suggests that psychologically based interventions are potentially beneficial for adults with chronic NeuP. An updated systematic review seems warranted.

Qualitative findings from a randomized trial of mindfulness-based and cognitive-behavioral group therapy for opioid-treated chronic low back pain

This article reports qualitative outcomes from a randomized controlled trial comparing eight weeks of cognitive-behavioral group therapy for chronic pain (CBT-CP) and mindfulness-based group therapy (MBT) in individuals with chronic low back pain (CLBP). Approximately 10 months post-treatment, 108 participants completed structured qualitative interviews to express how the study treatment affected their life or health. Responses were qualitatively analyzed to generate a set of themes and subthemes, with between-groups comparisons to evaluate differences (if any) in treatment-response between MBT and CBT-CP. A majority of participants (n = 88, 81.5%) across both groups reflected positively on the study intervention and outcomes, identifying benefits in pain management (31.5%), meditation and mindfulness skills (25.9%), and relaxation skills (22.2%). Perceived benefits varied widely, suggesting no one intervention may be ideal for CLBP. Future research should examine tailoring interventions to target diverse clinical presentations to achieve optimal outcomes.

Dealing with Chronic Pain: Tips to Teach Undergraduate Health Sciences Students

Chronic pain is a significant and costly problem all over the world that negatively impacts the quality of life of sufferers. There are clear discrepancies between the prevalence of chronic pain in society and the low priority assigned to educating future physicians about the complexities of pain. This condition also occurs in other undergraduate health science students, although research in this area has not been studied as much as in medical schools. Based on the International Association for the Study of Pain (IASP) Pain Curriculum Outline, a systematic search of the available literature, and the authors' own experiences, we highlight some relevant tips to educate health science trainees in the management of patients with chronic pain. These tips highlight current international recommendations for a comprehensive approach to this prevalent problem in society, which should be learnt during the university training of health professionals.

The Effect of Progressive Relaxation Exercise on Physiological Parameters, Pain and Anxiety Levels of Patients Undergoing Colorectal Cancer Surgery: A Randomized Controlled Study

PURPOSE

This study aimed to determine the effect of progressive relaxation exercises on physiological parameters, pain, anxiety, and serum cortisol levels in patients undergoing colorectal cancer surgery.

DESIGN

This study is a randomized controlled study and has been registered at the Clinical Trial Registry Center (ID: NCT04731428).

METHODS

The study was conducted on 63 patients (experimental group = 31, control group = 32), who were scheduled for elective laparoscopic-colorectal surgery in the general surgery clinic of a university hospital in Istanbul between March 2018 and May 2019 and met the inclusion criteria. The patients in the experimental group were given progressive relaxation exercises for 15 minutes preoperatively and on postoperative days 1, 2, and 3 after breathing exercise training. The routine treatments and care process of the patients in the control group were maintained. The preoperative and postoperative pain and anxiety levels of both groups were evaluated. Blood pressure, heart rate and respiratory rate, oxygen saturation, and serum cortisol levels were measured at certain time intervals before and after the relaxation exercise.

FINDINGS

The patients in the experimental group had lower postoperative pain and anxiety levels and a lower rate of using opioid analgesic on postoperative day 0 compared to the control group. Progressive relaxation exercise had no statistically significant effect on serum cortisol or physiological parameters (P > .05).

CONCLUSIONS

Progressive relaxation exercise did not affect cortisol levels and vital signs but decreased pain and anxiety, and relatively increased tissue oxygenation, appearing an effective, safe, and practicable nursing intervention.

Cognitive Change and Relaxation as Key Mechanisms of Treatment Outcome in Chronic Pain: Evidence From Routine Care

Despite effective treatment approaches within the cognitive behavioral framework general treatment effects for chronic pain are rather small to very small. Translation from efficacy trials to naturalistic settings is questionable. There is an urgent need to improve the effectiveness of well-established treatments, such as cognitive-behavior therapy (CBT) and the investigation of mechanisms of change is a promising opportunity. We performed secondary data analysis from routine data of 1,440 chronic pain patients. Patients received CBT in a multidisciplinary setting in two inpatient clinics. Effect sizes and reliable change indices were computed for pain-related disability and depression. The associations between changes in the use of different pain coping skills (cognitive restructuring, activity despite pain, relaxation techniques and mental distraction) and changes in clinical outcomes were analyzed in structural equation models. Pre-post effect sizes range from g = 0.47 (disability) to g = 0.89 (depression). Changes in the use of cognitive restructuring, relaxation and to a lesser degree mental distraction were associated with changes in disability and depression. Effects from randomized trials can be translated to naturalistic settings. The results complement experimental research on mechanisms of change in the treatment of chronic pain and indicate an important role of cognitive change and relaxation as mechanisms of change. Our findings cautiously suggest that clinicians should optimize these processes in chronic pain patients to reduce their physical and emotional disability.

Relaxation techniques as an intervention for chronic pain: A systematic review of randomized controlled trials

Chronic pain increases the risk of sleep disturbances, depression and disability. Even though medical treatments have limited value, the use of prescription-based analgesics have increased over the recent years. It is therefore important to evaluate the effect of non-pharmacological treatments. A systematic search for studies evaluating the effect of relaxation techniques on chronic pain was conducted. Randomized controlled trials were included. Significant effects on pain, or on pain and one or more secondary outcome measure, were found in 21 studies. Four studies found significant effects on secondary outcome measures only. Four studies showed no significant effects on any outcome measure. Thus, most of the studies reported that relaxation techniques reduced pain and/or secondary outcome measures. However, the included studies have evaluated effects across a wide variety of chronic pain conditions and relaxation techniques. Hence, there is a large degree of heterogeneity among the included studies. This complicates the effect evaluation and makes it difficult to draw a clear and unambiguous conclusion. Relaxation techniques are probably most effective when used through regular and continued practice. Future studies should therefore investigate long-term effects of relaxation technique interventions, evaluate the dose-response relationship and examine efficacy differences across pain conditions and interventions.

The Impact of Preoperative Distress: A Qualitative analysis of the Perioperative Pain Self-Management Intervention

PURPOSE

Preoperatively distressed patients are at elevated risk for chronic postsurgical pain. Active psychological interventions show promise for mitigating chronic postsurgical pain. This study describes experiences of preoperatively distressed (elevated depressive symptom, anxious symptoms, or pain catastrophizing) and non-distressed participants who participated in the psychologically based Perioperative Pain Self-management (PePS) intervention.

DESIGN

This is a qualitative study designed to capture participants' perspectives and feedback about their experiences during the PePS intervention.

METHODS

Interviews were semi-structured, conducted by telephone, audio-recorded, transcribed, and audited for accuracy. Coded interviews were analyzed using a quote matrix to discern possible qualitative differences in what preoperatively distressed and non-distressed participants found most and least helpful about the intervention.

RESULTS

Twenty-one participants completed interviews, 7 of whom were classified as distressed. Distressed participants identified learning how to reframe their pain as the most helpful part of the intervention. Non-distressed participants focused on the benefit of relaxation skill-building to manage post-surgical pain. Distressed and non-distressed participants both emphasized the importance of the social support aspects of PePS and- identified goal-setting as challenging.

CONCLUSIONS

Distressed and non-distressed participants emphasized different preferences for pain management strategies offered by PePS. Most participants emphasized the importance of social support that PePS provided.

CLINICAL IMPLICATIONS

Our results indicate that post-operative patients may benefit from interpersonal interaction with a trained interventionist. Our findings also suggest that distressed and non-distressed patients may benefit from varied intervention approaches. How to build flexibility into a manualized intervention or whether these subsets of patients would benefit more from different interventions is a direction for future research.

An exploratory clinical trial on acceptance and commitment therapy as an adjunct to psychoeducational relaxation therapy for chronic pain

Objective: The aim of this study was to compare the clinical efficacy of two differently-designed psychological interventions for chronic pain.Design: 138 patients presenting chronic pain were randomly assigned to one of two experimental conditions: (1) Psychoeducational relaxation therapy (PRT, n = 84) or (2) PRT followed by acceptance and commitment therapy (PRT + ACT, n = 54).Main outcome measures: Pain intensity, quality of life (SF-36), anxiety and depression (HADS), stress (PSS), pain catastrophizing (PCS), chronic pain acceptance (CPAQ), and psychological inflexibility (PIPS) were assessed at three time-points: before therapy (T1); at the end of the therapy (T2); and 3- months after the end of the therapy (T3).Results: In T2, the PRT intervention showed more significant improvements in the measures of mental quality of life [F (1,92) = 7.478, P < .05] and depression [F (1, 92) = 5.804, P < .05] compared to the PRT + ACT intervention. The experimental groups did not differ in their outcome measures at T3.Conclusion: PRT appears to be an effective solution in the psychological care of chronic pain. The effectiveness of this type of intervention seems to have been underestimated. The addition of ACT sessions did not significantly impact the results, indicating that both designs of interventions are effective in the short term.

Impact of mind-body treatment interventions on quality of life in neurofibromatosis patients: A systematic review and meta-analysis

Individuals with neurofibromatosis (NF) experience poorer quality of life (QoL), in part contributed by the clinical manifestations of NF, such as functional disability, chronic pain, and altered physical appearance. Mind-body therapies (MBTs) tailored to NF have been developed, and have demonstrated promising potential to improve QoL in this population. We sought to systematically review current evidence on the effectiveness of MBTs in addressing QoL deficits in NF patients. Databases were reviewed between the date of inception and June 2020, using search terms: neurofibromatosis, schwannomatosis, psychotherapy, mind-body, mindfulness, meditation, resiliency, and behavioral therapy. Quality appraisal was assessed using the Cochrane Risk of Bias Tools and National Institutes of Health Study Quality Assessment Tools. We conducted a meta-analysis of mean differences and reported aggregate effect estimates with 95% confidence intervals. A total of 10 articles, including randomized-controlled trials and pre-post studies, were identified. Meta-analytic results of randomized-controlled trial data from six citations demonstrated MBTs were associated with improved physical (MD = 13.63, 95%CI 6.95-20.30, P < .0001, I² = 24%), psychological (MD = 14.11, 95%CI 6.44-21.78, P = .0003, I² = 38%), social (MD = 9.63, 95%CI 2.93-16.33, P = .005, I² = 0%), and environmental QoL (MD = 14.14, 95%CI 8.28-20.00, P < .00001. I² = 0%) in NF patients. These associations were maintained at 6-months follow-up for physical, psychological, and environmental QoL (P < .05). Our findings suggest that NF-adapted MBT strategies are associated with improving QoL in diverse NF populations, including NF2 patients experiencing deafness and youth NF patients. Providers and caregivers for NF should be aware of the potential benefits of MBT in chronic NF management.

Touching the social robot PARO reduces pain perception and salivary oxytocin levels

Human-human social touch improves mood and alleviates pain. No studies have so far tested the effect of human-robot emotional touch on experimentally induced pain ratings, on mood and on oxytocin levels in healthy young adults. Here, we assessed the effect of touching the robot PARO on pain perception, on mood and on salivary oxytocin levels, in 83 young adults. We measured their perceived pain, happiness state, and salivary oxytocin. For the 63 participants in the PARO group, pain was assessed in three conditions: Baseline, Touch (touching PARO) and No-Touch (PARO present). The control group (20 participants) underwent the same measurements without ever encountering PARO. There was a decrease in pain ratings and in oxytocin levels and an increase in happiness ratings compared to baseline only in the PARO group. The Touch condition yielded a larger decrease in pain ratings compared to No-Touch. These effects correlated with the participants' positive perceptions of the interaction with PARO. Participants with higher perceived ability to communicate with PARO experienced a greater hypoalgesic effect when touching PARO. We show that human-robot social touch is effective in reducing pain ratings, improving mood and - surprisingly - reducing salivary oxytocin levels in adults.

Non-Opioid Perioperative Pain Strategies for the Clinician: A Narrative Review

Alternative and non-opioid options for pain management are necessary in perioperative patient care. Opioids are no longer touted as cure-all medications, and furthermore, there have been tremendous advances in alternative therapies such as in interventional pain, physical therapy, exercise, and nutritional counseling that have proven benefits to combat pain. The center for disease control now strongly recommends the use of multimodal analgesia and multidisciplinary approaches based on the individual needs of patients: personalized medicine. In this manuscript, the specifics of non-opioid pharmacological and non-pharmacological analgesic approaches will be discussed as well as their possible indications and uses to reduce the need for excessive use of opioids for adequate pain control.

Improving the self-management of chronic pain: COping with persistent Pain, Effectiveness Research in Self-management (COPERS)

Background

Chronic musculoskeletal pain is a common problem that is difficult to treat. Self-management support interventions may help people to manage this condition better; however, there is limited evidence showing that they improve clinical outcomes. Our overarching research question was ‘Does a self-management support programme improve outcomes for people living with chronic musculoskeletal pain?’.

Aim

To develop, evaluate and test the clinical effectiveness and cost-effectiveness of a theoretically grounded self-management support intervention for people living with chronic musculoskeletal pain.

Methods

In phase 1 we carried out two systematic reviews to synthesise the evidence base for self-management course content and delivery styles likely to help those with chronic pain. We also considered the psychological theories that might underpin behaviour change and pain management principles. Informed by these data we developed the Coping with persistent Pain, Evaluation Research in Self-management (COPERS) intervention, a group intervention delivered over 3 days with a top-up session after 2 weeks. It was led by two trained facilitators: a health-care professional and a layperson with experience of chronic pain. To ensure that we measured the most appropriate outcomes we reviewed the literature on potential outcome domains and measures and consulted widely with patients, tutors and experts. In a feasibility study we demonstrated that we could deliver the COPERS intervention in English and, to increase the generalisability of our findings, also in Sylheti for the Bangladeshi community. In phase 2 we ran a randomised controlled trial to test the clinical effectiveness and cost-effectiveness of adding the COPERS intervention to a best usual care package (usual care plus a relaxation CD and a pain toolkit leaflet). We recruited adults with chronic musculoskeletal pain largely from primary care and musculoskeletal physiotherapy services in two localities: east London and Coventry/Warwickshire. We collected follow-up data at 12 weeks (self-efficacy only) and 6 and 12 months. Our primary outcome was pain-related disability (Chronic Pain Grade disability subscale) at 12 months. We also measured costs, health utility (European Quality of Life-5 Dimensions), anxiety, depression [Hospital Anxiety and Depression Scale (HADS)], coping, pain acceptance and social integration. Data on the use of NHS services by participants were extracted from NHS electronic records.

Results

We recruited 703 participants with a mean age of 60 years (range 19–94 years); 81% were white and 67% were female. Depression and anxiety symptoms were common, with mean HADS depression and anxiety scores of 7.4 [standard deviation (SD) 4.1] and 9.2 (SD 4.6), respectively. Intervention participants received 85% of the course content. At 12 months there was no difference between treatment groups in our primary outcome of pain-related disability [difference –1.0 intervention vs. control, 95% confidence interval (CI) –4.9 to 3.0]. However, self-efficacy, anxiety, depression, pain acceptance and social integration all improved more in the intervention group at 6 months. At 1 year these differences remained for depression (–0.7, 95% CI –1.2 to –0.2) and social integration (0.8, 95% CI, 0.4 to 1.2). The COPERS intervention had a high probability (87%) of being cost-effective compared with usual care at a threshold of £30,000 per quality-adjusted life-year.

Conclusions

Although the COPERS intervention did not affect our primary outcome of pain-related disability, it improved psychological well-being and is likely to be cost-effective according to current National Institute for Health and Care Excellence criteria. The COPERS intervention could be used as a substitute for less well-evidenced (and more expensive) pain self-management programmes. Effective interventions to improve hard outcomes in chronic pain patients, such as disability, are still needed.

Can a brief educational intervention improve sleep and anxiety outcomes for emergency orthopaedic surgical patients?

Abstract An educational intervention (EI) is useful in preparing patients for orthopaedic surgery. This quasi-experimental study examined the effect of a brief EI on pain level, anxiety, pain inference on sleep, and sleep satisfaction among Chinese patients undergoing emergency orthopaedic surgery. The intervention group received usual care plus 20-minute EI which comprised a combination of patient education and a breathing relaxation exercise (BRE) whereas the control group received usual care only. The outcomes were evaluated before the EI and at days 2, 4 and 7 post-surgery. One hundred and fifty two participants completed the study. The intervention group had significantly lower pain levels (Brief pain inventory), anxiety levels (The Chinese state Anxiety scale), and lower pain inference scores on mood and better sleep satisfaction. Therefore, a brief EI with a breathing relaxation exercise is a feasible and useful intervention that can improve post-operative outcomes in emergency orthopaedic surgery.

Living with chronic low back pain: a metasynthesis of qualitative research

OBJECTIVES The purpose of this qualitative metasynthesis is to articulate the knowledge gained from a review of qualitative studies of patients' experiences of chronic low back pain. METHODS Meta-ethnographic methodology guided the review of 33 articles representing 28 studies published in English in peer-reviewed journals between 2000 and 2012. A systematic comparison of the main themes from each study was conducted and 'synthesised' to create superordinate themes. RESULTS Three overarching interrelated themes were identified: the impact of chronic low back pain on self; relationships with significant others that incorporated two streams - health professionals and the organisation of care and relationships with family and friends; coping with chronic low back pain. Coping strategies were predominantly physical therapies, medication and avoidance behaviours with very few successful strategies reported. Professional and family support, self-efficacy, motivation, work conditions and exercise opportunities influenced pain experiences. Review authors' recommendations included psychological therapies, education, the facilitation of self-management strategies and support groups. DISCUSSION The review substantiates chronic low back pain as complex, dynamic and multidimensional, underpinned by experiences of persistent distressing pain, loss, and lowered self-worth, stigma, depression, premature aging, fear of the future. Future research should address the paucity of longitudinal studies, loss and issues of ethnicity, gender, ageing.

The embodied and relational nature of the mind: implications for clinical interventions in aging individuals and populations

Considerable research over the past decade has garnered support for the notion that the mind is both embodied and relational. Jointly, these terms imply that the brain, physical attributes of the self, and features of our interpersonal relationships and of the environments in which we live jointly regulate energy and information flow; they codetermine how we think, feel, and behave both individually and collectively. In addition to direct experience, evidence supports the view that stimuli embedded within past memories trigger multimodal simulations throughout the body and brain to literally recreate lived experience. In this paper, we review empirical support for the concept of an embodied and relational mind and then reflect on the implications of this perspective for clinical interventions in aging individuals and populations. Data suggest that environmental influences literally “get under the skin” with aging; that musculoskeletal and visceral sensations become more prominent in activities of the mind due to aging biological systems and chronic disease. We argue that conceiving the mind as embodied and relational will grow scientific inquiry in aging, transform how we think about the self-system and well-being, and lead us to rethink health promotion interventions aimed at aging individuals and populations.
